Y 2B the huid-cooling radiator, 21 the iluid connection from the jacket 25 to the radiator, 28 the fluid connection from said radiator to said jacket, and 29 represents, generally, the usual pump for the fluid-cooling medium of an automotive vehicle 30 of any ordinary or preferred character. such as a pleasure vehicle, taxicab, bus, or truck. Ordinarily, the fluid-cooling mediumis circulated by the pump 29 from the jacket 25 through the connection 21 to the radiator 20. and back to um Jacket from the radiator-'through theY connection' 23.

In Fig. 1 o! the drawings, the novel and improved heating unit, designated 3l, is moimted within the interior of the automotive vehicle 30, numeral 32 indicating the dash of said vehicle upon which said heating unit is supported in a mannertobeiullysetiorth. As alsotobemade clear, suitable iluid conveying connections are provided whereby a part or all of the duid-cooling or circulating medium for the internal combus- Vtion engine of said vehicle isdiverted and utilined as the medium for supplying .heat to said unit 3|.

The heating unit 3i includes a duid-heated.

air-heating core consisting ai an upper iluid or vwater tank 33, a lower fluid or water. tank Il. a

' sirably being of slightly less Width than the width of the tanks 33 and 34. Said tanks are desirably of equal length and width. Theoutermost tubes 35 oi the different banks or sets oi tubes 38 and 39 are arranged adjacent the opposlte ends of the tanks, as very clearly disclosed, and all of said tubes 35 are parallely arranged. Each oi the iluid or water tanks 33 and 34 may desirably consist o! a header plate 40 into which the adjacent ends of the tubes 35 are' suitably fastened in fluid-tight fashion, as by soldering or otherwise, and a housing member 4| suitably fastened, also in huid-tight fashion, as by soldering or otherwise, to the marginal portions of the corresponding header plate 40, as very clearly shown in Figs. 5, 6 and 18. Each housing member 4I may be of about the configuration illustrated, or `of any other preferred shape.

The ilns 26, adjacent the opposite end portions of the core, are desirably of relatively small thickness, of width slightly greater than the width of the tubes, which may be of equal width, and of length about equal to the length of each tank. The ilns 31, between the two sets of tins 36, are of the same thickness as the fins 38 but are shorter, being in each instance arranged upon the tubes of but a single bank or set of tubes 38 or 39, as the case may be. The forward and rearward edges of the ns 31 desirably terminate ilush with the forward and rearward edges oi the ns 35, and the outer edges of said ns 31 desirably terminate ilush with the outer edges or said tins 36. The inner edges of the ns 31, terminate at the location of the innermost tubes 35 of the different banks or sets of tubes 38 and 39. 'I'he innermost ns 36 of the two sets of longer fins are desirably spaced apart a distance somewhat greater than the distance between the innermost tubes 35 of the two banks or sets oi tubes 38 and 39, and thus a rectangular space, designated 42, in the core and-between the banks or sets of tubes and surrounded by the ns, is

provided for a purpose to be made clear.

The tubes 35 of the different banks or sets of tubes are desirably spaced at equal distances from each other, and each ot said tubes 35 is desirably perpendicular to each header plate 40. with the widths of the tubes preferably disposed perpendicularly to a plane extending longitudinally land perpendicularly through both header plates.

The ns 36 and 31, respectively, are likewise desirably spaced at equal distances from each other, with the uppermost and lowermost fins 31 being spaced at this same distance from the adjacent longer fins 36, as will be clear from thev drawings. Said fins 36 and 31 may be associated with the tubes 35 before said tubes are secured to the header plates, by providing openings through the ns of size to fit the tubes, and sliding said fins over said tubes, or sliding the tubes through the openings in the ns. Preferably, the fins are secured to the tubes, as by soldering or otherwise, to be in intimate heat conveying contact therewith. v

When a core constructed as described is completed, it comprises a ,generally rectilinear article of about the shape as shown in the drawings, said article having opposite end portions thereof, constituted by theV housing members 4| of the tanks, constructed along somewhat curvilinear lines.

A supporting structure for the heating unit is adapted to be assembled with a single tubular or pipe support for said unit. The fluid or water tank 33 conveniently carries at the interior thereof a suitable bracket 43, said bracket being-riveted or otherwise secured, as at 44, to the upper Wall of the upper housing member 4|. A downwardly extending flange 45 of the bracket 43 includes a tapped hole 46 adjacent the rearward wall 41 of said upper housing member. A tubular or pipe support 48 has a threaded end portion 49 turned into the tapped hole 46, as disclosed very clearly in the drawings. The tubular or pipe support 48 extends through an opening 5'3 in said rearward wall 41, and a fluid-tight seal is provided betweensaid opening 50 and the'tubular or pipe support, as by soldering or otherwise. The bracket 43 is desirably constructed so as to spread over a considerable area o n the inside of the housing member of the upper tank 33, to provide a relatively Wide supporting structure for the heating unit. Also, the bracket 43 and the tubular or pipe jsupport 48 are of quite rigid structure, and when said tubular or pipe support is rigidly secured in the rearward wall 41 of the upper housing member 4|, as by'fsoldering, said tubular or pipe support is obviously fixed against turning movement in the bracket 43.

Referring more particularly to Figs. 1, 2, 3, 5, 6,v 7 and 8, numeral 5| denotes an electric motor within the space 42 of the heating core, said.7 motor having a blower or fan 52 fixed upon the motor shaft 53. The motor is of dimensions to nicely fit into the space 42, and the arrangement is such that the blower or fan 52 will be situated adjacent the core in fairly close relation thereto, about as illustrated in Figs. l, 3, 5 and 8. When electric power is applied from a source (not shown), such as the battery of an automotive vehicle, to the motor 5|, the blower or fan 52 is driven to force air through the core, past and over the ns and tubes thereof.

' Still referring to Figs. 1, 2, 3, 5, 6, '7 and 8, a

casing 54 is adapted to contain the assembly of the core, motor and blower or fan. Said'casing may more or less4 freely receive said core. As illustrated, the casing is a boxlike member consisting of a forward shell 55 and a rearward shell 56, which shells have a telescoping fit, vas at 51. The shells 55 and 56 together constitute a casing including straight side walls 58, curvilinear upper and lower end walls 59, and front wall 60 perpendicular to the side and end walls of the casing, with relatively large rectangular cut-away portion or opening 6| of area about equal to, or a little less than, and approximately similar to,tl1e over- 'all area covered by the forward surfaces or edges of the fins 36 and 31. 'Ihe back of the casing 54, constituted by the rearward shell 56, includes a flange 62 parallel with the front Wall 60, said flange 62, together with the adjacentportions of the'. rearward shell 56, constituting a shroud for the blower or fan 52 and/including a circular opening 63 'about said blower or fan. The core is inserted in the casing 54 so that said core is situated centrally of the cut-away portion lor opening 6| to completely cover said portion or opening.

A grille or air deilector 65 is arranged at the yfront of the casing 54 to cover-the forward area of the fins and tubes. That is to say, to cover the cut-away portion or opening 6|. In Figs. 3, 5 and 8, the grille or air deector 65 is separate from the forward shell 55 of the casingI 54. In, Figs. 6 and 9 the forward shell is a casting, and

the grill or air deector is'integral withv said forward shell. The grille or air deflector 65 as shown in Fig. 5 may include either stationary or adjustable bars or louvers. 'I'he bars or louvers of the grille or deflector of Figs. 6 and 9 are stationary. Several different types of grilles or air deiiectors are hereinafter described. Suffice it to say at this time that the grille or air deflector 65 as in Figs. 3, 5 and 8 includes a rectangular flange 66 adapted to be closely tted into the opening 6| in the front wall 60 of the forwardshell 55 of the said screw bolts 69 are so turned home, the peripheral fiange 61 and the rectangular ange 64 are drawn up tightly against opposite surfaces of the core, both when the forward shell 55 and the grille or air deflector 65 are separate as in Fig. 5, and when said forward shell` and grille or air deflector are integral as in Fig. 6, and the grille or air defiector, forward shell, core and motor with fan are h'eld in fixed relation.

In Figs. l to 8, the tubular or pipe support 58' constitutes cooperating means through the insrurnentality of which the heating unit can be mounted upon a xed part of an automotive vehicle body. As disclosed very clearly in Figs. 1, 5 and 6, the outer portion 16 of the tubular or pipe support 481s externally threaded and passes through a hole in the dash 32 of the automotive vehicle, said hole closely ti ing upon the tubular or pipe support. Said tubular or pipe support is rigidly secured in the dash of the vehicle by adjustable supporting nuts 1| upon the tubular or pipe support, there being one nut at each side of the dash, eachk of which nuts can be turned up against a washer 12 between the nut and the dash. The tubular or pipe support 48 passes through an opening in the flange .62, and a spacing sleeve 13 upon said tubular or pipe support 48 has one of its ends engaging the rearward surface of the upper housing member 4| of the core and its other end engaging said flange 62. A second spacing sleeve 14 upon the tubular or pipe support provision for the'rigidsecuring- 9d the QI'Q and'its casing, withi appurtenances, the automotive vehicle body, interiorly thereof.-.'lhe-weight of the grille or air deilector, the forward and rearward' shells of the casing, the shroud, the motor and the blower or fan are made rigid with the core, which, so to speak, carries said weight back to the tubular or pipe support 48. Referring to Figal, 3, 5,7 and 8, numeral l denotes a bracket or member cooperating with the tubularl or pipe support to ilxedly attach the heating unit to the dash 82. As there shown, said bracket or member l5 is of U-shape, including a leg 18 bolted to the dash, as at 11, and a leg 'i8 riveted to the ilange 62, as at 19, at location spaced from the tubular or pipe support 48. A tube or pipe 88 is secured in iluid-tight fashion, as by soldering or otherwise, in an opening 8i lin the rearward wall 82 of the lower fluid or water tank 84, and said tube or pipe 80, as well as the` tubular or pipe support 48, extends away from the core and out of the casing 42. An opening 88 in the flange 62, openings 84 in theA legs of the U-member 15, and an opening 85 in the dash allow passage of the tube or pipe 80.

In Fig. 6 a bracket 86, equivalent to the bracket l5, and for the same purpose, is integral with the rearward shell 58 and is bolted to the dash 82, as at 8l.A Openings 88, 84, and 85 in the flange 82, the bracket 86 and the dash 82 allow passage of the tube or pipe 80. I While the forward and rearward shells of the casing of Fig. 5 may desirably be composed of sheet metal, the forward and rearward shells of the casing of Fig. Bare castings, and the bracket 88 is cast integral with the rearward shell of said F18. 6.

Evidently, the arrangement as .illustrated in Figs. 1 to 8, and as before described, permanently retains the grille or air deilector, the forward and rearward shells of the casing, the shroud integral with said rearward shell of the casing, the core, and the motor with blower or fan in the proper and desired ilxed relation to each other. Thus, all of the Weight of the heating unit is carried yback to the tubular or pipe support 48 through the instrumentality of the heating unit core with which said tubular or pipe support is directly associated. The brackets or members, such as 15 or 8B, cooperate with the tubular or pipe support 48 to additionally insure stability of the lower portion of the heating unit.

A fluid'or water connection 88 extends from the tubular or pipe support 48 to the connection 28, at location in front of the pump 29, and a fluid or water connection 89 extends from Athe engine jacket 25 to the tube or pipe 80. When the internal combustion engine of the automotive vehicle 8U is operating, there will be a substantial flow of hot iluid or water from the jacket 25' through thevconnection 89 and the tube or pipe to the core of the heating unit, and back to said jacket 25 through the tubular or pipe support 48, the connection 88, the connection 28 and the pump 29. Any other suitable and preferred arrangement for circulating all or any desired portion of the hot iluid or water of the exiaoiaooo ginecoolingsystemthroughthecoreofthe ingunitcanbesubstitutedfortbe disclosed; Asillustrated,the ilowthroughtbo heatingunitooreisupward.

The hot fluid or water 10 upon entering the tube or .pipe 88 passes into the lower fluid or water tank 84. Thenoe hot fluid or waterpasses upwardly through each of -the relatively ilat and wide tubes. to the upper iluid or water tank 88. And from the tank 88. 15 the hot iluid or water passes out of the heating unit through the tubular or-pipe ,Support .48. While traveling through the tubes, I88, the hot iluid or water gives-off heat which is absorbed by the ilns. 88 and 8'|,and, by rotation of the 20 blower or fan 52 to force air pastand over the -ns or tubes, the air is caused'to be heated and,

distributed throughout. the vehicle-body.' l I f By reason of the provision ofthe separate banks or sets of relatively fiat end wide tubes '85, 25 the ht iluid or vwater is -cause'dto be circulated through theportion of the core. of theheating unit over which the circulatedlair travels at high velocity, 'I'he hot fiuidor water. thus its heat and causes the averagetemperatureofthe 3o heating unit to be elevated, so .that the heater functions capably and eillciently-at substantially the maximum capacity of heaters ofthe present general type which occupy considerably more space in automotive vehicle bodies.

It will be evident that by slight modification, the hot iluid or water could be circulated through the heating core by passing upwardly through the tubes of one of the banks or sets of tubes and downwardly through the tubes of the other bank nA or set of tubes. In such an event, the entrance and egress of hot iluid or water would be to and from the same tank, such as 83 or 34, and there would be a partition in this tank eil'ectually separating the adjacent ends of the difierent banks or 45;

sets of tubes. v

In Figs. 1, 2, 3, 5, 7 and 8,1 the grille. or air deilector 65 is of adjustable. type, and includes means for associating the device, representedSli,

adapted to convey warmed air to the windshield 50 the air passageways through the. heating core, 55Av each ofwhich openings in capable of receiving the device 90. Said device consists of'a flexible tube 92 having a desirably split coupling member y93 which can be removably iltted toi-,either hex.

agonal opening 9|, and an air distributing mem- 60 ber 94 including an obliquely extending air spreader 95 and flaring air directors 96. The arrangement is such that the air spreader directs the airA toward the windshield. and the air directors 96 cooperate with the air spreader 95 to cause 65 the air to travel over a preferred area oi' said windshield.. A clip 91 maybe employed to support the air distributing member adjacent the windshield. The blower or fan forces warmed air through the core of the heater and into the de- 7o vice 90, which conveys the hot air into contacting engagement with the windshield or other member to be de-frosted. 'I'he tube 92 being ilexible, the device 98 can be applied to any desired part of the windshield.` I

Said grille lor air deector of Figs. 1, 2, 3, 5, 7 and 8 includes vertically disposed bearings, indicated 98 and 99, at each side of the central strip 68, and a triangular shaped louver |00 is hingedly supported, as vat IOI, upon each set of bearings 99, 99. As disclosed, each'set of bearings 98, 99 supports a vertical shaft |02 upon `which a louver |00 is fixed; and a coil spring |03 upon each shaft |02 and between the louver I 00 and its lower bearing surface insures that each of said louvers |00 will remain at any adjusted position to which set, as will be understood. The triangular louvers |00 are adapted to together cover a portion of the opening 6I at the upper location of said opening and at either side of the center strip 68. Said louvers I 00 are also adapted to cover ythe hexagonal openings 9|. The grill or air deector additionally includes obliquely disposed bearings |04 and |05, at the outer, oblique edge of each triangular louver |00 when in closed position, and a triangular shaped louver |06 is hingedly supported, as at |01, upo'n each set of bearings |04, |05. As disclosed, each set of bearings I 04, |05 supports an oblique shaft I 09 upon which a louver |06 is fixed, and a coil spring |09 upon each shaft |00 and betweenthe louver I 06 an'dits lower bearing surface insures that each of said louvers |06 will remain at any adjusted position to which set. 'I'he triangular louvers |06 cover allof the remainder of the opening 6| not covered by the triangular louvers |00. The oblique outer edge portions of the louvers |00 slightly overlap the oblique inner edge portions of the louvers |06, and the vertical outer edge portions of the said louvers |06 slightly overlap the sideframe members of the grille or air deector 65, as shown very clearly in Figs..2, 3 and 8, when in closed position. Thus said louvers |00 and |06 effectually preclude the passage of air through the heating unit when the louvers are closed. Obviously, each louver |00, |00, |06, |06 is separately adjustable upon its hinge, and the louvers can be set to deflect air passing through the heating unit in any preferred direction. And the louvers can be set to permit the passage of any amountv of air from the heating unit. That is, some louvers can be closed, some partially open, and some fully open at one and the same time, depending upon preference. Clearly, when the device 90 is inserted in either hexagonal opening 9|, the louver |00 for this opening is swung to open position, as in Figs. 1 and 3, and devices 90 can be positioned in both openings 9|, as when it is desired to concurrently warm two separate locations upon a windshield or other member.

While louvers Y |00 and |06 of specific structure x a casting. Fig. 10 is a front elevational view of casting.` In Figs. 9 and 11, the grille or air de-l ector 65 includes a pair of sets of stationary bars or louvers IIO arranged at the opposite sides of or less freely receive said core.

the center strip 68, which bars or louvers are as disclosed situated obliquely to extend downwardly and toward said center strip, and are arranged atan angle, as shown in Fig. 13, t'o deilect the air toward each side of the heating unit, and hence toward opposite sides of an automotive vehicle.

in which said heating unit may be situated. That is, there are two divergent sets of air cui-rents, and the air is deflected downwardly as well as outwardly. The construction described provides a xed or stationary type of deflector for the heating unit which will satisfactorily accomplish proper distribution of the air at small cost for the deflector. In Figs. 11 and 12 it will be seen that the hexagonal openings 9| in a stationary deflector may be constructed in aboutv the same manner as when an adjustable deflector is employed.

Fig. 14 discloses a grille or air deflector made of sheet metal and including `stationary bars or louvers III situated obliquely. Said bars or louvers I I I are arranged at an angle, as best disclosed in Figs. 15 and 16, to deflect air toward a side of the heating unit and downwardly. The

-shaft II4. The motor II2 is of dimensions to nicely t into the space 42, and thearrangement is such that the blower or fan I I3 will be situated adjacent the core as shown in Fig. 18, said blower or fan II3 being at the side of the core opposite the side at which `the blower or fan 52 is situated. When electric power is applied from a source (not shown), such as a battery of an automotive vehicle, to the motor I I2, the blower or fan is driven in the direction denoted by the arrow in Fig. 17 to pull air through the core as disclosed by the arrows in Fig. 18, past and overA the fin and tubes of said core. I

Still referring to Figs. 17 to 21, a casing I|5 is adapted to contain the assembly of the core, motor and blower or fan. Said kcasing I I5 may more As illustrated, the casing is a box-like member including straight side walls II6, curvilinear upper end wall II'I, relatively straight lower end wall IIB, and rear Wall II9 perpendicular to the side and end Walls of the casing, with relatively large .rectangular cut-away portion or opening |20 of area about equal to, or little less than, and approximately similar to, the overall area covered by the rearward surfaces or edges of the fins 36 and 3l. Said rear wall I I9 includes an integral center strip i I 2| which extends vertically across the midwidth of the rectangular opening I 20. The front of the casing I I5 supports a cover or shroud |22 for the blower or fan H3, the inner portion of said cover or shroud being in telescoping relation to the front of the casing, and the cover `or shroud and the casing being bolted or riveted to each other as at |23'. The cover or shroud |22 includes an inwardly extending flange |24 parallel with the rear wall IIS, and said flange |24 includes a circular opening |25 about the blower or fan I I3. The core is inserted in the-casing I I 5 so that said core is situated centrally of the cutaway` portion or opening |20 to completely cover said portion or opening, and so that the blower soy or fan is adiacent the circular opening |25, in alinement therewith..l Said opening |25 is deiined by an annular flange |26 extending forwardly from the ange |24of the cover or shroud |22.

As disclosed'very clearly in Fig. 18, the motor ||2 includes a peripheral iiange |21 which is located adjacent the blower or fan H3. Numeral |28 denotes a reinforcing strip or plate arranged against the outer or rearward surface of the center strip |2i, at the midlength of said center strip. Said'reinforcing strip or plate |28-and said center strip |2| have alining openings therein to receive spaced apart screw bolts |28, as disclosed in Figs. 18 and 19, which screw bolts are adapted to be turned home into the adjacent surfaces-of said motor i2 that is, those surfaces opposite the blower or fan I i3. When said screw bolts |28 are so turned home, the pheripheral flange |21 and the center strip |2| are drawn up tightly against opposite surfaces of the core, and the casing, core, cover or shroud and motor with blower or fan are held in fixed relation.

A circular grille or air defiector |30 is arranged I at the front of the cove'r` or shroud |22, and is suitably fitted to the annular iiange |26 over the circular opening |25. As shown very clearly in Fig. 21, said grille or air defiector |30 includes an annular ange |3| fitted over the annular flange |26. Additional means (not shown) may be provided for fastening the grille or air deiiector |30 to the cover orshroud |22. Said grille or airdeiiector |30 may be-constituted as a casting, or may be sheet metal. VAs shown, it includes a pair of sets of stationary bars or louvers |32 arranged at the opposite sides of a vertical centerline of the grille or air deiiector, which bar or louvers are situated obliquely to extend downwardly and toward said center line, and are arranged at an angle, as will be clear from Fig. 2l, to deflect the air toward each side of the heating unit and downwardly.

In Figs. 18 and 19; the tubular or pipe support 48 constitutes means through the instrumentality of which the heating unit can be mounted upon an automotive vehicle body. The outer portion 10 of the tubular or pipe support is externally threaded and passes through a hole in the dash 32, said hole closely tting upon the tubular or pipe support. Adjustable supporting nuts 1| upon the tubular or pipe support rigidly secure it in the dash. One nut 1| is arranged at each side of the dash, and each nut is turned up against a washer 12 between the nut and the dash. The'tubular or pipe support 48 pases through an opening in the rear wall H9. The' arrangement as described rigidly secures the core and its casing, with appurtenances, at the interior of the automotive vehicle body. lThe weight of the grille or air deiiector, the casing, the shroud, the motor and the blower or fan are made rigid with the core, and said core carries said weight back to the tubular or pipe support 48, as stated in connection with Figs. 1 to 8. The tube or pipe 80 passes freely through the opening 85 inthe dash 32 and through an opening in the rear wall H9.
